Description

Technical Field

[0001] The utility model relates to the technical field of waist-protecting cushions, in particular to a waist-protecting cushion with flexible support. Background Art

[0002] Traditional ergonomic chairs have strong support. Since they do not deform, the support force of the chair is usually concentrated at the contact points between our body and the chair, such as the upper back and the sitting bones. Over time, this can easily cause fatigue and pain in these areas.

[0003] Chinese Patent Publication No. CN217243374U discloses an ergonomic chair, which relates to the technical field of chairs and includes an ergonomic support frame, wherein the top front side of the ergonomic support frame is fixedly connected to a chair back sponge component, and the bottom top of the ergonomic support frame is fixedly connected to a chair seat sponge component. The ergonomic support frame is integrally formed by a backrest, a neck support, two groups of shoulder support parts, a lumbar support part, and a hip and leg part. Since the neck support part is gently concave inwardly from both sides, each group of shoulder support parts is convex facing the side of the human body, the lumbar support part is concave outwardly facing the side of the human body, and the edges of the hip and leg parts are gently tilted upward, in actual use, when a human body sits on the ergonomic support frame, the human body's shoulders, waist and buttocks can be wrapped, and a plurality of groups of convex strips are symmetrically fixedly connected to the front side of the lumbar support part, which can make the backrest part bear more weight. The structure is designed according to ergonomics to increase the comfort of the user.

[0004] The neck support part of the above technology is gently concave inward from both sides, which can support the human neck, but the structure has poor air permeability, and it is easy to sweat and feel tired after sitting for a long time. Therefore, the utility model discloses a flexible support waist cushion to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a lumbar support cushion with flexible support, which solves the technical problem that the neck support part of the traditional ergonomic chair is gently concave inward from both sides, which can support the human neck, but the air permeability of this structure is poor, it is easy to sweat after sitting for a long time, and it is easy to feel tired.
